Hi there @Andrei!
The boots you purchased were likely the Merrell Phaser Peak Hiking boots, which Merrell no longer makes. If you look at the product carousel under the product description on the link, you'll see several similar boot styles that are offered by REI. It doesn't look like we are getting any more of the GTX version of the Merrell Moab any time soon, however, the Merrell Moab 2 MID waterproof hiking boots are in stock in your size.
One word of caution about the Merrell Moab: it is a significantly more flexible boot than your Phaser Peak boots so you'll want to be aware of that if you are looking for support and rigidity in your boots. We would encourage you to take a look at the Merrell Forestbound Mid Hiking boot or the Merrell Ontario Mid Waterproof hiking boots.
Hopefully this helps, thanks!
